Hello once again and welcome to my next lesson, which is we am where you and I have created this lesson.
Specifically, on the upon request of my students, a lot of students asked me, can you tell us a little
bit more about being where virtualization technology is?
So anyway, I'm taking some time to go over what really VMware is.
VMware is basically the name of the company as it is, and its product name is also VMware.
So we were incorporation is a public, publicly traded software company.
You could look it up online and you're going to find its stock if you wanted to buy it.
VMware provides cloud computing and virtualization software and services.
We already talked about virtualization.
The virtualization, the main function of the main products of VMware is actually virtualization.
They also have a cloud computing.
If you wanted to host your applications on their cloud, on their virtualization software, where everything
is on their data center, then you go with the cloud computing.
So it was one of the first commercially successful companies to virtualize the 86 architecture.
That statement is right off the Wikipedia.
You could look it up as well.
If you just type what is VMware, you're going to find that statement in there as well.
Now, we are where software allows users to create multiple virtual environment or virtual computer
systems on a single computer or server.
So those who are familiar with the virtualization technology, you guys do know that the virtualization
technology is basically allow you to run multiple virtual machines on a single hardware.
VMware does the same thing.
It's just the name of the company is different from other virtualization technology and how VMware still
owns 60 to 75 percent of the market share, meaning a lot of companies in the world.
They actually using almost like 60 to 75 percent of the market.
Now, let's look at the VMware products and tool and see what are the terms or technologies they use
to make the virtual environment or from for any company.
So lets see you bring a hardware, you have a hardware regardless of who the manufacturer is, whether
it could be HP or Dell server.
So that's actually a hardware.
When you get at a hardware, usually it does not have any operating system on it.
Now I know when you go outside and buy your personal computer or your laptop, it does come with an
operating system.
But in the real world, in a corporate world, bigger servers don't come with any type of software or
operating system.
So you have to install an operating system.
So again, back in the days when there was no virtualization technologies, you would install one operating
system and then be done with it and you stuck basically with one server if it's underutilized.
That's the problem, if it's overutilized, that was great, but anyway, so what was it?
You have a hardware and on top of the hardware, you install some type of operating system for Rehame,
where you would install the operating system called IACI.
Now, this is a hyperbolizes software.
Maybe they don't refer it as an operating system, but I'm just telling you as an operating system,
because for you to understand it easier that you do need some type of software in order to communicate
with your hardware.
So that IACI server, when you install it, it actually could ask you to go through all the Wizards.
And at the end of the Visored, it will actually ask give you this screen, as you could see on the
right hand side, a yellow screen.
It will also ask you to provide the IP address, the username, password, DNS information subnet,
subnet mask, when a whole bunch of information.
So you could actually once that is set up, you could actually access that ESX isover using something
called Vecepia.
That's this is a client that you need to access that ESX size sobre.
Now if you're using an older version of ESX I, which is like five or six, then you could use actually
VMware vs Fertik client.
But if you're using the newer version, I would say about I think sixty two or sixty five, the newer
version of this.
So I knew where John XXIII, they do not work on the for a client.
Then you need to access that IACI through the Web browser.
So you put in the IP address of the success over the web browser opens up and it will show you this.
Where then if you wanted to add it, multiply your success over.
The reason you want to add multiple ESX isover is what if one ESX server goes down and it has 10 VMS
running on it, then you lose all those tensions.
Right?
So that's what they got together again and they said, you know what, we got to fix this issue.
And in order to fix this issue, we could have multiple ESX servers work together as in a cluster now.
OK, perfect.
Now, which software will manage that cluster?
So first they they said, OK, let's put all those ESX isover together and we're going to manage that
through a software called a V Center.
The V center is the one that will manage all three of them and then we'll put them in a cluster.
All right.
Moving on now, once you have that cluster, once everything is set up, you use the same VMware client
because V Center is a management software that uses the same voice for a client to access all those
servers.
So when you said this is how it looks like, you could just simply I just got this picture off the Internet.
It's it's not mine or I am not trying to steal someone's picture.
It's just that I got this picture online.
It was free, so I just used it for my training to.
Anyway, when you access it or your environment recentre using the voice for your client, this is how
it will look like on the home page.
You notice this one has a V center.
It will tell you everything about the V center that you have installed.
The second one has Hosten clusters, which will tell you how many server holes hyperbolizes we have
and how many clusters we have in, and also how many clusters and how many hosta we have in that cluster.
Then VM and templates.
When you click on it, it will give you the list of all the VMS that you are running in your environment.
The storage of the storage is something that is attached to your hypervisor, to your host.
You do the networking.
You could also do virtual networking.
And there are some other tools that are available with that.
And then it has monitoring.
If you want to know what is going on with your environment, you could check with the monitoring and
you could do also sys administration task, meaning who can access what and what kind of services.
If you see on the left side, there is a left side tree which tells you that pretty much the same thing,
but it's a shortcut way to access all those different menus.
So this is how the center looks like.
If you have not seen it, you can also I would say I recommend you could also go to the YouTube and
look for some of the tutorials where they gave you a walkthrough of the center or vice, where you probably
going to find those tutorials from the beginning where directly.
So that's great.
They they have done a great job explaining it.
So if you want to learn more, I would definitely recommend you go there on their website and look or
understand how these center or Vesuvio works.
Good luck.
And if you have any questions, let me know.
Thanks.
